Don't consider it as a serious OC, it's just an Idea. Organizzation XII as 13 members: Xemnas, Xigbar, Saix, Vixen, Zexion, Laxaeus, Marluxia, Axel, Luxord, Larxene, Demyx, Xaldin, and, at last, Number 13: Roxas. I tought # 0 as Ansem the Wise's Nobody, thinking that Xemnas was Xehanort's one. As Roxas, he use two Keyblades: One Small, One giant. The name is just unknown, for now. The giant Keyblade is quite random, in the future I will remake this as a official OC
